Abstract
A formaldehyde scavenger for environmental type, in described formaldehyde scavenger, contained composition consists of by weight percentage: ammonium acetate 10-15%, sodium acetate 5-8%, sodium chloride 5-10%, ammonium carbonate 5-8%, glacial acetic acid 1-2%, surfactant 1-5%, all the other are water.The invention has the beneficial effects as follows, first this scavenger itself is nontoxic, next is at room temperature to react rapidly with formaldehyde, effective removal formaldehyde reaches more than 98%, and is irreversible reaction, and finally this scavenger and formolite reaction obtain hexamethylenetetramine compound, this compound is stable under pH value neutrallty condition, and soluble in water, available wet towel wiping removing, is convenient to cleaning.
Description
Technical field
The invention belongs to technical field of chemistry, relate to a kind of formaldehyde scavenger, particularly a kind of formaldehyde scavenger of environmental type.
Background technology
Formaldehyde is indoor main volatile organic compounds (VolatileOrganicCompounds, one of VOCs), have carcinogenic danger, therefore its removal is most important to the health improving indoor air quality and the mankind, has become one of problem be very concerned about in the world.Formaldehyde was classified as first kind carcinogen in 2004 by international cancer research institution (ARC).Formaldehyde causes the nasopharyngeal carcinoma of the mankind, CARCINOMA OF THE NASAL CAVITY and nasal sinus cancer, can cause leukaemia.Along with the enhancing of people's environmental consciousness, the formaldehyde discharged in artificial board more and more causes the attention of people to the harm that human body causes, formaldehyde in urea-formaldehyde resin adhesive makes us insufferable penetrating odor, all has spread effect to schneiderian membrane, retina and the upper respiratory tract.It can generate nitrogen methylene compound with proteins react and change the character of protein, can cause slow poisoning, pathology and allergic reaction infringement health.For a long time, the harm of the finishing pollution harmful substances such as formaldehyde progressively understand by people, indoor formaldehyde multi-source is in all kinds of artificial board, and coating and paint are also containing certain formaldehyde, formaldehyde is more highly toxic material, and on China's toxic chemical priority acccess control list, formaldehyde is in second.Formaldehyde has been defined as carcinogenic and cause deformed material by the World Health Organization, be generally acknowledged allergen, is also one of potential strong mutagen.
There are some at present about the technological invention eliminating formaldehyde, such as: application for a patent for invention numbers 200410037055.6 discloses a kind of formaldehyde catching agent, containing urea in the formaldehyde catching agent described in document, urea be can with formolite reaction, but this reaction belongs to reversible reaction, out, just play the effect temporarily removed, be not fundamentally eliminate to all right slow release of the product that urea and formolite reaction obtain.Describing the main component removing formaldehyde in application for a patent for invention numbers 200610017363.1 and 200810210246.6 is amino acid, amino acid can generate methylene imino derivative with formolite reaction, but spendable amino acid whose kind is less in practical application, and its cost is higher, and amino acid and formolite reaction products therefrom whether poisonous, need further textual criticism.
Summary of the invention
Object of the present invention is exactly the formaldehyde scavenger in order to provide a kind of environmental type.
The technical solution used in the present invention is, a kind of formaldehyde scavenger of environmental type, in described formaldehyde scavenger, contained composition consists of by weight percentage: ammonium acetate 10-15%, sodium acetate 5-8%, sodium chloride 5-10%, ammonium carbonate 5-8%, glacial acetic acid 1-2%, surfactant 1-5%, all the other are water.
In the present invention, ammonium acetate and ammonium carbonate are mainly used in removing formaldehyde, can react rapidly with formaldehyde; Sodium acetate and glacial acetic acid form cushioning liquid jointly, for regulating solution ph to neutral; Surfactant plays osmosis, this product can be made effectively to penetrate in furniture, eliminate formaldehyde better; Sodium chloride, as auxiliary ingredients, can change the viscosity of surfactant, and its critical micelle concentration and surface tension are changed, thus improves the surface-active of surfactant.
The invention has the beneficial effects as follows, first this scavenger itself is nontoxic, next is at room temperature to react rapidly with formaldehyde, effective removal formaldehyde reaches more than 98%, and is irreversible reaction, and finally this scavenger and formolite reaction obtain hexamethylenetetramine compound, this compound is stable under pH value neutrallty condition, and soluble in water, available wet towel wiping removing, is convenient to cleaning.
